Was wondering is there a particular reason why some of the plans and photos shown/offered have a narrow top of the oven while others offer an deeper top in use?

If I understand your question, the top depth (narrow top) is simply a design option.  In my opinion, having a thinner top piece that then joins with another angular piece is an unnecessary complication (although, it would result in dropping the overall height by a couple of inches).   This adaptation could also result in slightly better stove performance.  However, from my experience, the single piece, V-shaped top produces reasonably quick cooking times.

Ultimately, it just a matter of establishing enough overall depth to be able to accept the cooking pan you are using.
